OpenSandbox
Alibaba CloudApache-2.0 sandbox runtime from Alibaba aimed squarely at AI agents, defines a 'Sandbox Protocol' with standard lifecycle/execution APIs and ships multi-language SDKs (Python, Java, JS, .NET) plus Docker and Kubernetes runtimes. Picked by teams wanting an open protocol-driven alternative to E2B at K8s scale; ~10.8k stars and 910 commits in the last 90d signal serious investment.

Adoption
2 low confidenceOnly ~2-3 months old; no PyPI/download or named-deployment figures surfaced. ~11.3k GitHub stars (3,845 within 72h of launch) is the only signal, stars_fallback, which caps level at 3. Placed at 2: rapid early stars but no usage volume yet. Revisit as usage data emerges.

Capability
3 medium confidenceBroad multi-language SDK surface and MCP integration with K8s scale, but container-level isolation (no VM/microVM tier observed) keeps it mid-tier on the isolation-strength dimension vs Firecracker/gVisor/Kata. Strong breadth, moderate isolation.
